11.The Sunken City
Egypt is famous for its giant pyramids rising in the desert,but some of the nation's treasures from the past are hidden underwater.It is on the ocean floor near Egypt's northern coast (33)that a long-lost city of more than 2,700years old lies.Now researchers are bringing its remains to the surface to share the sunken civilization with the world.
Clues to the Past
Some ancient texts describes a city called Heracleion,(34)which was located at the mouth of the Nile River and disappeared beneath the waves 1,200years ago.But for centuries,no one knew for sure if such (35)an unbelievable city ever really existed.Then in 2000,Scientist Frank Goddio and his team discovered the ruins of the city.Since then,to uncover the city,they have been busy removing layers of sand,which had kept many of its treasure well (36)preserved(preserve).They've uncovered gold coins,jewelry,giant statues,ships and a sign.These items provide clues to help find out (37)what life was like in Heracleion.
Secret of the Deep
But so far,the sinking of this city remains a mystery.Goddio isn't sure how the city sank.He thinks that earthquakes or tidal waves (38)might have caused it to fall into the sea."Stories from long ago tell of other cities in this area disappearing because of either or (39)both of those things,"explains Goddio.
With many of Heracleion's treasures still buried under the sea,it may be many years before all its secrets (40)are revealed(reveal)."We've barely scratched the surface with this city."another scientist Robinson says.
